Possible approaches may include: New York: ASCE, Coastal Sediments 77, pp. (a) (i) Use Figure 2 to describe variations in the percentage of properties at risk from coastal erosion and flooding. Ability to show change over time? [5], Three areas identified on the map south-west/northeast/ north-west) - not all are needed. Climate change. As people migrate to the coast for residences, business, and recreation, they interact with the natural coastal environments. Knowledge and understanding of conditions and process of deposition In this study, we attempt to address this issue by simulating the spatial interactions among natural hazards, ever-increasing human activities, and social vulnerability in the south coast of the Bohai Sea, China. The sandy beach consists of two zones, the swash zone and the drift line. Focus is on differences in deposition rather than comparison of deposition and erosion. The content will depend upon the example or examples given but there are a number of threads that will be common for credit. - leading to decrease in overall erosion (1) 293303. Beaches move back and forth onshore, offshore and along shore with changing wave conditions. Concerns arising from the pollution of coastal and marine waters from land based sources are well established. The increase in the use of fertilisers for agriculture and warming ocean waters has contributed to eutrophication of the Ocean in certain areas of the world. Getting these measures right is not easy and requires transformative, multidisciplinary research, with an aim to support sustainable and responsible ocean stewardship for the conservation of the environment and to ultimately improve lives. The world has woken up to the millions of tonnes of plastic that have entered the Ocean over the past 100 years. [3], global increase in temperatures in interglacial periods Cliffs provide inputs into beach In: Pye K, Allen JRL (eds) Coastal and estuarine environments: sedimentology, geomorphology, and geoarchaeology. This erosion may be very apparent or seem to have happened overnight when it happens due to a large storm or extremely high tide. This means there is less available dissolved oxygen for native sea life, which can negatively impact biological processes. That means the choices we make can have a positive or negative impact on the Ocean. Also a great place to retire examples include Bournemouth and Blackpool. Headland has developed A conclusion may be drawn in the context of the landform(s). Material from beach can be transported to other beaches, 17. A ghost net trapping fishes and other creatures on a coast. There graph shows distinct zones that could be used to identify patterns. 3.6 billion People live near or around a coast. Many of these are primarily the result of human actions and include ecosystem and landscape changes, sedimentation, pollution, over-abstraction and climate change.. reference to types of reefs - fringing, barrier, atoll There are even implications now as they add more sand. Certain fishing practices not only contribute to overfishing of their target species, but also damage the environment by dredging the seabed or catching other species that are thrown back dead. [5], chalk cliffs steeper than clay and sand, 3. ), Coastal and Estuarine Environments: Sedimentology, Geomorphology, and Geoarchaeology. [10]. Content may vary according to landform(s) selected but may include: the importance of human intervention such as management strategies and sea level rise, 10. fetch controls the size of the waves The following discussion will consider some of the more obvious and problematic human impacts. (a) Use Figure 2 to describe the varying impacts of coastal erosion over time. This can be dangerous for kids and adults alike who are not careful when in the water, The erosion of shorelines is a natural process that can have beneficial or adverse impacts on the creation and maintenance of habitats. This is more than half the worlds population. This is a preview of subscription content, access via your institution. Knowledge and understanding of other processes such as wind, fluvial, estuarine, erosional process, human influence etc. Enviromental organisations have tried there best to limit the amount of man made deveoplment on coastal lads and many schools, Preserving coastlines is important for the economy and the environment. Accept both routes. Aeolian transportation is when the wind transports sediment. Sediment starvation caused by river and coastal management is one effect of human activities on the coast. It is found that the activities occurring on . Shows distribution clearly? Coastal sediments 87. Special publications, vol 175. Examination of the relative role of longshore drift . [3], Presence of unconsolidated sand - some places may have more sand dunes which are more prone to wind erosion - large particles The coastline is rapidly eroding at an average of 1.8 metres a year. This has been successful in reducing the amount of sand that is drawn out to sea. Key scales? Location 1 has most decrease/erosion and greatest range - 210.65.88.143. Used to compare different areas, and they are a useful visual aid as they can show differences clearly the development of bays by erosion can provide shelter for shipping, 8. Many human activities take place on the coast; The effects of these may be: Direct or indirect; Positive or negative; Table of Impacts on Coasts. Answers may conclude that longshore drift has a major part or variable influence on the development of selected landform(s). knowledge and understanding of the reasons why a management strategy is required such as erosion of coastal dunes by tourists, destruction of coral reefs, erosion as a consequence of the use of groynes knowledge and understanding of the characteristics of the management strategy which could include physical structures and operations These characteristics may be linked with the processes that are part of the development of the landform such as weathering, marine erosion and mass movement AO2 By the time new sand was brought to the beach in 1991 to replenish what was eroded, there was hardly anything left. Loss of farm land in the southern section of the photograph The need for extra grazing is putting pressure on wildlife. 2. the development of coral reefs and mangrove coastlines may attract tourists and lead to the development of a tourist industry Erosion of the 12 apostles (only 9 left) has nothing to do with humans, where dramatic oil spill near coast ruins beaches, does have to do with humans. The human cost of flooding can be large, but events like this have a big impact on the natural world too, and the effects are not always negative. - Decrease in wave height leads to decrease in wave energy (1) magnitude of process changes with spatial scale Sand dunes act as a natural barrier against coastal storms and beach erosion caused by strong, destructive wind and waves. Human activities have had an impact on coastal environments almost as long as people have been using the coast. [5], High energy characteristics: the characteristics of the strategy such as physical structure or operation Coastal regions are highly vulnerable to the impacts of human activities, land cover change, sea level rise (SLR), and climate extremes. They can think, reason, feel and make deductions or hypothesis and seek to solve or prove their deductions or theories. (c) Outline how coastal sediment is transported by traction. Significant areas of loss are located from 33 km to approximately 48 km reaching as low as -1.5 per year. Use of colour in key? Assessment of the positive impacts of human activity in different places within one location or between locations The relationship between humans and their environment is a topic that engenders much debate. A new study suggests that exposure to coastal environments can play a significant role in boosting human health and well-being, due to the therapeutic effects marine and coastal landscapes have. This is more than half the world's population. The specification lists these as beaches, spits, bars, tombolos and cuspate forelands. An examination of the role of other processes Superimposition of circles makes interpretation difficult and confusing - 161.35.97.149. The content may vary according to the landform but may include: Examples could be stacks, arches, and wave cut platforms but credit any relevant landform. building of groynes or dredging could affect depositional rates, 8. the role of biotic factors -Use of colour, interpretation easy? Landforms that could be identified include fjords, rias or raised beaches. The finer-grained silts and clays derived from the erosion of shorelines are sorted and carried as far as the waters of wetlands or tidal flats, where benefits are derived from addition of the new material. Erosion of wave cut platforms provide inputs into beach [6]. A new issue facing the Ocean is that of deep sea mining. Wed like to set additional cookies to understand how you use GOV.UK, remember your settings and improve government services. A lot of the seawalls and groins were buried in order to form the new beaches. the impact on the aesthetics of the coast An examination of the role of marine processes over time in the formation and subsequent modification of the chosen landform/s. Since the industrial revolution, humans have increased carbon dioxide in the atmosphere to levels that have caused Ocean acidification and Ocean warming, amongst other climate related negative effects. geographical context Arrowed explanations will assist the candidate to reach Band 3. [3], - presence of unconsolidated sand 2. (b) Describe two distinctive features of a geo. The content may vary according to the landform but may include an examination of: Great news for a joined up global effort to protect the Ocean. The content will depend upon the impact chosen and may include: Protection of cliffs by a variety of management strategies - groynes, sea walls etc. This has happened for many year. "To fail the Amazon is to fail the biosphere, and we fail to act at our own peril." #amazon #humanimpact #agriculture #deforestation #landusechange Indicative content Ability to pick out anomalies 1. Candidates should show knowledge and understanding of negative impacts such as pollution of waters and beaches, factors that can influence deposition in a negative way e.g. Around the foreshore of both Long Beach and Nutgrove Beach, rocks have been added to the foreshore to prevent further erosion of the beach. Major cities like New York are right next to the sea. [15], AO1 melting of glaciers (eds. An examination of the role of marine processes in the formation of a suite of landforms. The, Coastal Erosion is a natural process that takes place along the nations coast causing a loss of sediments in some places and deposits in others.3. Protection, management and conservation of dune systems - replanting . Overbuilding and extensive paving of shorelines can result in destruction of habitats and disruption of land-sea connections such as sea-turtle nesting spots. [5], wave height reduced with increased distance inland for all forests, 4. loamy sand -Does it provide specific information about the related event, ie strength etc Assessment of the level of positive impacts with variations of economic input There are several reasons why the coast at Holderness is eroding so quickly: Bridlington is protected by a 4.7 km long sea wall . Knowledge and understanding of the characteristics of identified landform(s) of coastal deposition. Changes in Earth's climate have different effects in different areas of the world. They can think, reason, feel and make deductions or hypothesis and seek to solve or prove their deductions or theories. . 12. Journal of Coastal Research, 14: 407417. [6], Possible approaches may include: 2019, p. 247). [6], Generally increased erosion over time in the south of the photography (reference to dates) the development of dramatic scenery by erosional processes may attract tourists and lead to the development of a tourist industry This may include: glacial weight removed from land (b) Discuss the impact of either eustatic or isostatic sea level changes on the development of one coastal landform. These processes could be sub aerial and/or marine, transport or depositional processes. The drift line is formed by the dead seaweed and other aquatic plants. The formation of landforms over one or more of these time scales should be related to processes. [5], greatest in Newport -Beaches, Give your answer to 2 decimal places. Anyone you share the following link with will be able to read this content: Sorry, a shareable link is not currently available for this article. The Great Barrier Reef is under threat from a range of pressures with a major one being deteriorating water quality due to pollution from adjacent land use. Coral reefs AO2 content encompasses the application of knowledge and understanding to assess the relationship between human activity and positive impact. The sandy beach is the junction of land and ocean. 15. This means that natural wildlife or landscapes are being cut down to be used for humans. -Mouth, building groynes, or human factors that influence coastal erosion in a negative way e.g. Wetlands are constantly adjusting to disturbances occurring within them and within the surrounding landscape. e.g. (a) (ii) Suggest one social loss associated with coastal erosion. provision of sediment as erosional tools Around the world, many projects are now seeking to restore marine habitats, such as mangrove and seagrass. ) Suggest one social loss associated with coastal erosion in a negative way e.g in deposition rather than of.
